Hey, I am hoping someone can help me with a power supply rebuild. I am dealing with a ALS 17" Imac G5 Power Supply part #614-0365. I replaced all the bad caps but noticed a blown zener diode at position ZD6. I could not decipher any color bands, and so I am flying blind here. I searched the forum and found one other person with the same problem, same location but different variation of the same power suppply. His best guess was a 3.6 volt zener diode. Any help would be greatly appreciated, thanks Steve.

Re: Help identify blown Zener diode in Imac G5 power supply.
Please identify the PSU by the board number. They used different boards in many of the same number casings. (if that makes any sense
)
ID Appears as this: API3PC96
Do not go by the number on the label on the casing. 1,000's of these were refurbs by the factory and cases were swapped. Case has nothing to do with it working, just if it fits a 17" or 20".
Please give a location for this part. Top or bottom (SMD) of board? Nearby component? Or a picture is the *best*.

Re: Help identify blown Zener diode in Imac G5 power supply.
I tested ZD6 on a scrap board that is I think the most common type of 17" PSU with the ID API3PC94
I measured ZD6 to be 26.5v
Not that this is going to help you if your board is another model.Comment

Re: Help identify blown Zener diode in Imac G5 power supply.
Found the diode in another thread and looked at mine. By the code, it's ~16v. I'd have to pull it to test it on the bench.
If that diode is cooked, you have some other serious problems.

Hi
all
I have a usb rechargeable hair trimmers that should work plugged in and charge
it stopped working no led norhing
I've opened it up and see the tp4056 chip has blown
There is a zener diode that I tested and get a near short ohms reading no matter which way my leads are
I don't know what to replace this with
Please help
thanks so much... -
Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.
So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.
Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
The led strips has 9 6V leds.

I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.
The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.
It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.
I think an issue could be a zener diode (or capacitor) which has shorted out.
The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the... -
My Element 32 inches tv (ELEFW328B) lost it's backlight (confirmed with a flashlight test) and the connector on the PCB (it has one board that has a processor chip, switch mode power supply, and backlight circuit) that has the two wires that go to the backlight LED strips has a very low voltage (28-29 volts) when turned ON, in my opinion.
Started testing components and found an SMD diode or zener that is shorted (even zero fusing resistors read a few tens of milliohms, while this thing reads zero).
I put some pictures here to show that it is labeled "M7"....
